| 摘 要： | 根据榆林市樟子松种子园建立以来的水分管理档案和抽样调查数据,分析了灌溉对母树生长及结实的影响。结果表明：灌溉能明显促进母树营养生长,也可在一定程度上提高结实数量。回归分析结果进一步表明降水量以及水热平衡关系是影响母树生长的主导因子。

| Abstract: | The effect of irrigation on growth and fruiting of mother trees was analyzed based on the water management record and spot check data of Yulin Municipal Seed Orchard of Pinus sylvestris var.mongolica.The results showed that irrigation significantly enhanced the vegetative growth of mother trees and induced the quantities of seed setting in degree.Regression analysis results also showed that the precipitation and water-energy budget was the key factor affecting the growth of mother tree. |
